Waiting for the results of a full system, especially since I mounted up a full Akrapovic yesterday.

The real aspect is not so much the increase in torque and horsepower but the fact it makes those improvements across basically the whole Rev range that means a massive increase in response and acceleration without going beyond the 4 HP gains initially those are good enough for most people

i notice the Yam R7 makes 76hp stock with most journalists fawning all over Yamaha Reps - this is a proper sports bike and is a bargain, thanks for showing

I really foresee an interest in 500-550cc sportbikes in the near future. This category was all the rage in the early to mid 80's and with todays tech could make for an exciting ride once again.

It’s just crazy that emission laws are strangling that bike that much.

Flashed ecu gets you to 72 to 75 hp at rear wheel. Does slip on or full system add any power? No other mods, love sound of slip on is full system worth it?

would you have any info on gearing? I was hoping to get shorter gearing to get more acceleration and torque to give up some of the HP. Is that possible?

A slip on? What if uses graves full system ti headers would make more 6-7hp right?

Quick question @2wheeldynoworks would the smog block off plates offered by graves, make any gains, with the slip on, air filter,& your tuning?

Data is never irrelevant!!! You’re doing a public service with each run lol. Each run in each variation will be of massive help to some rider & his tuner somewhere, guaranteed.

Would I need to get it remapped if I did your ecu tune but then later added the same slipon & air filter after?

Don't hold out - what full systems do you have coming ? The Graves slip-on is tempting, but a near 10 pound weight loss (Akrapovic) with a full system is more so. I've had my 4RR for a week now, and no matter what the critics say, it's worth it.

Isn’t this almost entirely because the US model is basically factory detuned? Now it essentially makes 2/3 the HP of a stock 600, with 2/3 the displacement.
